HPI212S Compact High-definition Loudspeaker

The HPI212S is designed to deliver "big bass" to small and medium sized venues from a package that is easy to integrate within modern venue architecture. Stylish and practical the HPI212S also features a very smooth frequency response and the audio performance is more in the class of a much larger format system.

A Closer Look

The first obvious attributes of the HPI212S are build quality and thoughtful design. The speaker transducers are custom built 12" drivers and are one of the very few loudspeakers with cone material made from Australian eucalyptus hardwood. This material has strength like a composite material but the warm sound of a cardboard cone; much loved by hi-fi enthusiasts. The benefit with the Quest driver is it can take serious punishment while still sounding like high end studio.

Power handling is high and the 2 x 12" front-loaded low profile sub-bass enclosure delivers enhanced sub bass and great percussive "punch" you would normally expect from a much larger format system.


Under the Stage or in the Air

Practical considerations for installers and live sound engineering were high on the designer’s priority list. The sloping connector recess on the back of the casing makes it possible to install the casing against a wall and also protects the cable connectors from possible damage. The sloping panel also acts as a cable strain relief for added reliability and great for a tidy installation.

Multiple reinforced M10 threaded inserts around the casing make it possible to fly the HPI212S for permanent installation.

For mobile sound, a 35mm speaker pole adaptor is installed on the casing.


Power Me Up

The HPI212S is a serious sub. Quest Engineering recommends an amplifier capable of delivering 800-1200W (nominal) to ensure full performance. The perfect solution are Quest's QA2004, QA3004 or the new QX4500.
